Named for its type locality at the Susanna mine at Leadhills in Scotland. Leadhillite is an uncommon mineral in oxidized lead deposits and in addition to Scotland, can be found in England, Austria, the United States, Namibia, and Australia among several others. Leadhillite can fluoresce a pale yellow under ultraviolet light. It will decompose in hot water. Heating will result in a reversible alteration to susannite.

Lefontite is a new IMA mineral described in 2014 (IMA 2014-075). This is the type locality but it was also found at the Palermo mine.

Named for a Belgian mine engineer known only as a Mr. Legrand, who was the first to collect the mineral. An uncommon mineral that occurs in oxidized zinc-arsenic bearing deposits, and can be found, albeit rarely, in granite pegmatites. Localities for Legrandite include in Mexico, Namibia, the United States, Japan, and Brazil.

Leif Ericson, the famous Norse adventurer and discoverer of Greenland is the namesake for Leifite. It is a rare mineral that occurs at its type locality in the Narssarssuk pegmatite in Greenland, at Mont Saint-Hilaire and the Strange Lake complex in Canada, and in the Kola Peninsula in Russia. It is found in pegmatites, alkali massifs, and in a gabbro-syenite complex.

Named after Tomas Leighton Donoso, a Chilean mining engineer and Professor of Mineralogy at the University of Santiago in Chile. Leightonite is a rare mineral found only in Chile, Namibia, and at newer localities in Austria, and Norway. It occurs at its type locality at the Chuquicamata mine in Chile in oxidized copper under low acidity conditions.
